При перемещении поршня цилиндра, соединенного с винтом, происходит вращение гайки и валка. Если необходимо непрерывное вращение валка, каждый валок должен быть снабжен двумя гидроцилиндрами, а если допустимы остановки, можно применить один цилиндр на каждый валок [1J.When moving the piston of the cylinder connected to the screw, the nut and the roller rotate. If continuous rotation of the roll is necessary, each roll must be equipped with two hydraulic cylinders, and if stops are permissible, one cylinder can be applied to each roll [1J.

Недостатком конструкции является большое число цилиндров, следовательно, сложность гидравлической схемы.The disadvantage of the design is the large number of cylinders, therefore, the complexity of the hydraulic circuit.

Цель изобретения - упрощение констру-_мкдии и снижение ее металлоемкости.The purpose of the invention - konstru- _m kdii simplification and reduction of its metal content.

Устройство работает следующим обра- 20 зом.The device operates as follows.

При вращении барабанов 11 и 18 приводами, соответственно 12 и 19, общая лента 10 с барабана 11 перематывается на барабан 18 и этим самым толкает 25 ролик 17. Он, в свою очередь, через траверсу передает усилие на винты 15 и 20, которые, получая поступательное движение, вращают одновременно в разные стороны за счет правой и левой резьбы гайки 30 и 21, связанные с прокатными валками 1 и 2 устройствами 29 и 30 типа храпового механизма. Кроме того, винты и 20 при поступательном движении через, например, толкатель 31 выводят 35 винты 7 и 22 с траверсой 8 и роликом в исходное положение для совершения реверса. Реверсирование происходит при вращении барабанов 11 и 18 в обратном направлении. В зависимости от длины и 40 толщины ленты зависит максимальная длина прокатываемого материала.When the drums 11 and 18 are rotated by the drives 12 and 19, respectively, the common tape 10 from the drum 11 is rewound onto the drum 18 and thereby pushes the 25 roller 17. He, in turn, transfers the force through the crosshead to the screws 15 and 20, which, receiving translational motion, rotate simultaneously in different directions due to the right and left thread nuts 30 and 21, associated with the rolling rolls 1 and 2 devices 29 and 30 of the type of ratchet mechanism. In addition, the screws and 20 during translational movement through, for example, the pusher 31 lead 35 screws 7 and 22 with the crosshead 8 and the roller to its original position for reversing. Reversal occurs when the drums 11 and 18 rotate in the opposite direction. Depending on the length and 40 thickness of the tape, the maximum length of the rolled material depends.

В случае, когда траверса 8 соединена с лентой 23, лента 26, наматываясь на барабан 18, разматывается с рулона 27, а лента 23, разматываясь с барабана 11, наматывается на рулон 24. Наматываясь на барабан 18, лента 26 толкает ролик 17 с траверсой 16, которая в свою очередь, передает усилие на винты 15 и 20, а дальше все происходит аналогично описанному.In the case when the traverse 8 is connected to the tape 23, the tape 26, being wound on the drum 18, is unwound from the roll 27, and the tape 23, being unwound from the drum 11, is wound on the roll 24. Winding on the drum 18, the tape 26 pushes the roller 17 with the traverse 16, which, in turn, transfers the force to the screws 15 and 20, and then everything happens as described.

Claims

The invention relates to ferrous and non-ferrous metallurgy, more specifically, to rolling mills for the production of sheets and long products. A rolling mill is known, which includes a bed, rolls with cushions, nuts connected to them, interacting with screws, traverses, and a drive for the translational movement of screws. When moving the piston of the cylinder connected to the screw, the nut and the roll rotate. If continuous rotation of the wapka is necessary, each roll should be provided with two hydraulic rotors, and if stops are allowed, one cylinder can be applied to each roller of Li. A design drawback is the large number of cylinders, hence the complexity of the hydraulic circuit. The purpose of the invention is to simplify the design and reduce its metal intensity. The goal is achieved by the fact that the drive is made in the form of driving drums, with the common ribbon 4 wound on them in the form of rolls, and the drums are in contact with the end surfaces of the mentioned screws through the tapes and traverse. In addition, the drums are installed on both sides of the working stand, and the belt is made common to both drums. . In this case, the ribbons are made of variable thickness, which determines the mill speed control program. FIG. 1 shows a rolling mill; in fig. 2 - the same, the embodiment of the roll; in fig. 3 is a view A of FIG. 1. The rolling mill consists of work rolls 1 and 2. installed in cushions 3 and in a bed 4. Pillows are supported on screws 5. In the first case, roll 1 is equipped with a nut 6 that interacts with the tongue 7. A rectangular head of this state is installed in the traverse 8 (Fig. 1). Traverse 8 is connected by means of a roller 9 with a common tape 1O, partially wound on a drum 11 with a drive 12. A nut 13 and 14 are installed in the lower roll 2. The nut 14 communicates with a screw 15 and an engraving 3S 16 connected by means of roller 17 with common lenga 1O, which was used on a drum 18 with a drive 19. With traverse 16, a screw 20 and a nut 21 of the upper roll 1 are connected. With the crossbar 8, a screw 22 cooperating with a nut 13 and a lower roller 2 is connected. Traverse 8 can be connected by means of a roller 9 with a belt 23 partially wound on a drum 11 with a drive 1 in a roll 24 with a drive 25 (Fig. 2). In the lower roll 2, there is also installed a nut 14, which interacts with screw 1 and crosshead 16, connected by means of roller 17, with tape 26, wound on a drum 18, driven 19, and partly on angle 27, driven 28. A screw 20 and nut are connected to crosshead 16 21 of the upper roll 1. The device operates as follows. When the drums 11 and 18 rotate, drives 12 and 19 respectively, the total tape 1Q from the drum 11 rewinds the drum 18 and thereby pushes the roller 17. It, in turn, through the traverse transfers the force to the screws 15 and 2O, which receive a progressive The movements are pressed simultaneously in different directions by the right and left threads of the nut 14 and 21, which are connected with the rolling rolls 1 and 2 by devices 29 and 30 of the ratchet type. In addition, the screws 15 and 20 in the forward movement through, for example, the pusher 31 re-enter the screws 7 and 22 with the crosspiece 8 and the roller 9 to the initial position to complete the reverse. Reversal occurs when the reels 11 and 18 rotate in the opposite direction. Depending on the length and thickness of the tape depends on the maximum length of the material being rolled. In the case where the yoke 8 is connected to the belt 23, the belt 26, winding reel 18 on S4, is unwound from a roll 27, and the belt 23, unwinding from a drum 11, reels onto a reel 24. Reeling on the drum 18, the belt 26 pushes roller 17 with crosshead 16, which in turn transmits force to screws 15 and 2O, and then everything happens as described. The proposed drives can be operated on low-speed reversing rolling mills. Tapes on the drums can be done. variable thickness defining the mill speed control program. Claim 1.
